http://www.hare.org/links/saturday.htmlEver since I visited Dr. Robert Hare in Vancouver, I can see them, the psychopaths. It's pretty easy, once you know how to look. I'm watching a documentary about an American prison trying to rehabilitate teen murderers. They're using an emotionally intense kind of group therapy, and I can see, as plain as day, that one of the inmates is a psychopath. He tries, but he can't muster a convincing breakdown, can't fake any feeling for his dead victims. He's learned the words, as Bob Hare would put it, but not the music.

For his first paper, now a classic, Hare had his subjects watch a countdown timer. When it reached zero, they got a "harmless but painful" electric shock while an electrode taped to their fingers measured perspiration. Normal people would start sweating as the countdown proceeded, nervously anticipating the shock. Psychopaths didn't sweat. They didn't fear punishment -- which, presumably, also holds true outside the laboratory. In Without Conscience, he quotes a psychopathic rapist explaining why he finds it hard to empathize with his victims: "They are frightened, right? But, you see, I don't really understand it. I've been frightened myself, and it wasn't unpleasant."

Hare made another intriguing discovery by observing the hand gestures (called beats) people make while speaking. Research has shown that such gestures do more than add visual emphasis to our words (many people gesture while they're on the telephone, for example); it seems they actually help our brains find words. That's why the frequency of beats increases when someone is having trouble finding words, or is speaking a second language instead of his or her mother tongue. In a 1991 paper, Hare and his colleagues reported that psychopaths, especially when talking about things they should find emotional, such as their families, produce a higher frequency of beats than normal people. It's as if emotional language is a second language -- a foreign language, in effect -- to the psychopath.

He calls them "subclinical" psychopaths. They're the charming predators who, unable to form real emotional bonds, find and use vulnerable women for sex and money (and inevitably abandon them). They're the con men like Christophe Rocancourt, and they're the stockbrokers and promoters who caused Forbes magazine to call the Vancouver Stock Exchange (now part of the Canadian Venture Exchange) the scam capital of the world. (Hare has said that if he couldn't study psychopaths in prisons, the Vancouver Stock Exchange would have been his second choice.) A significant proportion of persistent wife beaters, and people who have unprotected sex despite carrying the AIDS virus, are psychopaths. Psychopaths can be found in legislatures, hospitals, and used-car lots. They're your neighbour, your boss, and your blind date. Because they have no conscience, they're natural predators. If you didn't have a conscience, you'd be one too.
